This is a continuation of reissue application Ser. No. 308,710 filed Nov. 22, 1972, and now abandoned. swimming rolls already known. Swimming Rolls of the type disclosed in U.S. Pat. No. 2,908,964 dated Oct. 20, 1959 and sold under trade name "Swimming Rolls" and the registered trademark "Kusters Swimming Rolls". The pressure of the squeezing roll may be controlled.
The breadth leaving the squeezing rolls or the squeezing station B passes the return roll and advances below the dye applying unit which, in FIG. 1, has been designed in the same manner both for the wetting equipment and said dye applying equipment, comprising a trough 3', a feeding 4', a roll 5' with its appropriate drive and the scraper 7', said roll immersing into a dye liquid 10 contained in the trough 3', and said scraper contacting the roll throughout its length and the breadth throughout its width, scraping off from the roll the dye liquid taken along from the roll out of the trough, and passing the dye liquid onto the pile face of the carpet. The direction of rotation of the roll has been marked by the arrow 6'. The rotating speed of the roll 5' may be continuously controlled. In the same manner the liquid level to be maintained in the trough may be controlled.
A majority of dye applying means may be arranged in a sequence. In FIG. 1 a second dye applying equipment has been indicated.
The breadth leaving the dye applicator passes between the rolls 11 and 12 of which roll 11 has been designed as a grooved roll. The grooves are comparatively close to each other. In the embodiment shown the width of the grooves is 1.5 mm. and the distance between the grooves is also 1.5 mm. The depth of the grooves is 3 mm. The grooved roll may be replaced by another grooved roll with another groove dimension to satisfy all requirements. FIG. 3 is a sectional view of a grooved roll.
The grooved roll may also be a roll having a rubber cover or a repulsive cover such as polytetrafluorethylene, as may be seen in FIG. 4. The flexible cover has been identified by 13.
Instead of a grooved or comb roll it may even be possible to provide a scraper 14 in the form of a comb a sectional view of which is shown in FIG. 5. Even the rake may be provided with a rubber cover or a similar one such as a polytetrafluorethylene cover. The rake must be inclined towards the direction of the running breadth in which case the end contacting the breadth is slightly bent off in the same direction.
The breadth leaving the pair of rolls 11 and 12 is sagging in the form of a loop 15 and is pulled off via a sag control from the same into the direction of the arrow E.
The difference between the embodiment according to FIG. 1 and that according to FIG. 2 is that, in FIG. 2, a trough 16 has been provided for wetting the breadth, said trough containing the wetting liquid 17. The carpet is passed through the wetting agent via the roll 18 and by means of the roll 19 located within the trough.
